    Hello@vikas, It's always recommended to use a bleeder of 100 ohms. Vout of the part has an offset of around 250mV due to a leakage in no-load condition. The 100-ohm bleeder will pull it down.

    Hellovikas Nagpal,

    It’s always recommended to use a bleeder of 100 ohms.

    Vout of the part has an offset of around 250mV due to a leakage in no-load condition.

    The 100-ohm bleeder will pull it down.

    If there’s no issue with 250mV offset the part can be used without bleeder also.

    If there’s a concern with effectiveness while using a 100-ohm bleeder also a 500-ohm bleeder can be used. 500-ohm bleeder will have an offset of 65mV.

    Please go to Options for Target in Keil also-

    1) Go to the Device menu and add your device TLE9872QTW40 also uncheck the BF stepping to make the code compatible with your device.

    Go to Debug menu-> Settings-> Flash Download and confirm if TLE9872QTW40 with 252k size is selected.

    2) Now open the config wizard, go to PMU-> Power Saving Modes, select Sleep mode, and save it.

    3) Rebuild your project and check page 0 with address 0x1103F000.

Hello,

I’m trying to come up with a system to perform wear leveling in the Dflash EEPROM (AURIX TC265).

After going through the user manual, example code, and a few other posts in this forum, the correct way of writing to Dflash is (Please correct this if it’s wrong)

1. Erase entire sector( 8KB)

2. Enter Page mode with the page address

3. Load data to be written

4. Write page/ write burst.

Repeat steps 3 and 4 until the needed amount of data is written to DFlash.

The data that I want to write to Dflash isn’t further than 32 bytes in total. So, I was looking for a technique to spread out these 32 bytes written in the logical sector( 8192 bytes) itself every time I need to store a new dataset. Is this possible? Or am I limited to spreading out my writes across sectors and not on the page level, as erase command works only on the sector level and not on the page level?

Thanks

    Hi Vikas. Yes, that is a common issue. You do not need to fill the whole sector at once; you can incrementally write pages until the industry is full.

    Hi Vikas.

    Yes, that is a common issue. You do not need to fill the whole sector at once; you can incrementally write pages until the industry is full.

    The tricky part is avoiding the erase disturb effect and dealing with the possibility of word line failures, as described in 10.8.3.1 Robust EEPROM Emulation on page 1000 of tc26xB_um_v1.3.pdf. For example, it’s impossible to have one set of static manufacturing data written once in DF0, and one set of dynamic data; all data must be periodically rewritten to avoid erasing disturbs.

    Thank You

We’re seeing a positive pulse in pin 6.5 while powering up, resetting & programming (via SWD). Please see the attached screenshots.

The pin is port 6, which also has SWD and reset lines. We tested the pin with various configurations via PSoC creator, but could not find out the root cause. Can anyone help us in correcting this issue?

    still, also I suggest an average worth resistor( 100K?) drag-down to GND If this is your project case.
